The probability would be 0.9738.
We first find the z-score for each end of this interval:
z = (x-μ)/(σ/√n) = (100-110)/(18/√49) = -10/(18/7) = -3.89
z = (x-μ)/(σ/√n) = (115-110)/(18/√49) = 5/(18/7) = 1.94
Using a z-table (http://www.z-table.com) we see that the probability that a score is less than the first z-score is 0. The probability under the curve to the left of, less than, the second z-score is 0.9738. Subtracting these we find the area between them:
0.9738 - 0 = 0.9738.
Answer:3 & 4
Step-by-step explanation: those are the two with multiplication/division
Total shells Sandy had = 5
Shells Mageret got = 3
Balance of Seashells
5 - 3
2
It will need to be 9 as 27 by 8 is 216 and 23 by 9 is 207 and the you subtract 207 from 216 and get 9
